We collect trace data from a **dotnet** application with opentelemtry. Everything looks fine as expected. The use cause is checking the Observability =\> APM =\> Service whenever there is an issue or performance degradation.

My question is related to index\_mode settings. The current and default `index_mode` is **Standard** for `traces-apm@template`. I wonder the followings.

- Is it makes sense to switch to [LogsDB](https://www.elastic.co/search-labs/blog/elasticsearch-logsdb-index-mode) or [time series](https://www.elastic.co/docs/manage-data/data-store/data-streams/time-series-data-stream-tsds) index mode?
- What is the important points that I should check before change the index mode?

Cluster information:

- The CPU usage on hot nodes is ~%20 on average.
- There are two hot nodes and a frozen node.
- ILM is set to keep data 7 days in hot nodes and move to the frozen node and remove data after 90 days.

**Install method** : Elastic Cloud  
**Elasticsearch version** : 9.0.0  
**APM Server version** : 9.0.0

Hi @Musab_Dogan good question  
`traces-*` should be left in standard mode... they have not been test / not support with logsdb mode.
